CONCRETE BUILDING FORM.

Application filed June 6,

To all whom it may concern Be it known that I, PAUL J. HUEBER, a citizen of the United States of America, of Syracuse, inthe county of Onondaga, in the State of New York, have invented new and useful Improvements in Concrete Building Forms, of which, the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to concrete building forms of the class set forth in my Patent #1,t21,236, June 27, 1922, in that the main object is to provide a temporary form composed of standardized easily portable sections capable of being rogressively and rapidly assembled from t 1e bottom upward one or more stories to enable the walls, floors and partitions to be progressively cast or molded from concrete into a unitary or monolithic structure and to be expeditiously stripped and reassembled in other parts of the same building or in different buildings as the concrete work is finished.

One of the specific objects is to provide simple and eflicient means supported by the studs at one side of a wall for receiving and supporting the panels at the opposite side of the same wall and thereby to avoid the necessity of duplicating the studding at both sides of the wall, resulting in a considerable saving of-time, labor andmaterial.

Another object is to provide a more convenient and expeditious mechanism for looking the studs and floor joists to the girders and also for locking the meeting ends of sectional girders to each other, whereby the wall faces of the studs and girders and the floor faces of the joists and girders including those of the girder sections, may be properly alined to produce the desired smooth finish of the adjacent surfaces of the wall and floor and at the same time to enable those parts to be easily and quickly detached one from the other when it is desired to strip them from the walls.

Other objects and uses relating to specific parts of the forms will be brought out in the following description.

In the drawings,Figure 1 is a perspective view of the inner portion of one corner of 1923. Serial No. 643,742.

Figure 5 is a sectional view taken on line 55, Figure 4.

Figure 6 is an enlarged detail sectional .view taken on line 6-6, Figure 1, show- 111g the means for connecting the lower end of the stud to the lower girder'together with one of the tie bolts for supporting portions of the outer wall form.

Figure 7 is an enlarged detail horizontal sectional View taken on line 7-7, Figure 1, showing the means for connecting the adjacent ends of the girder sections.

Figure 8 is a sectional view taken on line 8-8, Figure 7, except that the girder sections are shown full width.

Figure 9 is an enlarged detail horizontal sectional view in the plane of one of the tie bolts showing portions of the opposite wall forms and one of the spacing members partly broken away together with the means for clamping the outer panels against the adj acent end of the spacing. members.

Figure 10 is aperspective view of a portion of one of the bearing. plates for the edges of the adjacent outer panels.

In order that the various adaptations of this ini'ention may be clearly understood, I haveshown portions of the form as used in the construction of one of the upright corner walls and floor of a building although it will be evident that certain parts of the same form may be used in the construction of the concrete partitions, as a unitary or monolithic part of the walls and floors as will be hereinafter more fully explained.

As illustrated, the form comprises lower and upper girders 1 and -1- Suit ably supported in parallel horizontal planes one above the other, a distance corresponding approximately to the required distance between the floors of the building, said girders being constructed of comparatively light channel steel bars of substantially the same cross sectional'size and form. I p t The lower girder '1- may be supported edgewise vertically upon a previously constructed concrete footing-course arwhich may be a part of the foundation of the building or one of the concrete floors thereof, which is to become a part of the monolithic structure, said girder being arranged with its fiat side facing the space in which the concrete wall is to be constructed so as to constitute a part of the form for said wall.

It is necessary to make these girders in sections for convenience in handling and to couple the sections together end to end in exact alinement with each other, and in or-- der that this may be clone expeditiously, the channelled sides of the adjacent ends of the sections are provided with coupling members 3- and 4 riveted or otherwise permanently secured to their respective sections, as shown more clearly in Figures 7 and 8.

The section 3- preferably consists of an angle iron having its base flange riveted to the web of the girder -l and its other flange offset laterally some distance beyond the longitudinal edges of the flanges of the girder, and provided with a stop shoulder -5, and a transverse slot 6-- just at the outside of the shoulder 5 for receiving a tapered key or wedge --7.

The other coupling member 4 is also" provided with a base flange riveted or otherwise secured to the web of the girder and has a lateral offset terminating in a longi tudinally extending hook-shaped extremity I .key 7 may be driven into said slot to simultaneously wedge against the outer end of the extension 8- by which operation,

the adjacent ends of the girder sections will be alined with ach other, both vertically and transversely, and will be rigidly ient for handling which is determined by actual experience sothat the size of the panels and consequently the spacing of the brackets'-1()*,"and construction of various other parts of the form may be standardized for all ordinary classes of work.

A plurality of upright studs 11 corresponding in number to the number of brackets lO-are supported at their lower ends upon the upper faces of the girders 1- and brackets -10 as shown'more clearly in Figure 6, and it therefore, "follows that these studs will be arranged in spaced relation, lengthwise of the girders, a distance between the centers of the brackets to assist in supporting the panels as -12--, in upright positions aswill be hereinafter more fully described.

The brackets l0 extend outwardly some distance beyond the flanges. of the girder and constitute coupling members for cooperation with companion coupling member -13 on the lower ends of the studs equal to the distance between theinner face of the girder and outer face of the bracket -10 so that when the stud rests upon the girder with its inner face substantially co-incident with that of the girder, itsouter face would be substantially e o-incident with the outer face of thebracket.

This bracket is provided with a boss 14 projecting outwardly beyond its outer face and provided with a transverse slot 15 for receiving a tapered key or wedge 16. V V

The coupling member ---13 preferably consists of a cast metal plate secured by rivets or equivalent fastening means to the outer face of the stud --11- and extended downwardly beyond the lower end of said stud so as to overlap upon the corresponding outer face of the bracket '10 and is provided with a vertical slot -17 opening from its lower end for receiving the boss 141- and permitting the key l6 to wedge tightly between the outer'face of the coupling member 13 and outer wall of the slot -15- thereby securely fastening the lower end of the stud to the girder and also permitting said stud to bereadily Hit) removed from said girder by simply withdrawing the key.

The lower face of the bracket l O is disposed in substantially the same horizontal plane as that of the girder +1- so as to rest upon the concrete footing-course awhile the upper face rises to the height of the level .of the corresponding face of the girder, but is beveled outwardly and downwardly to form a seat for vthe lower end of the stud and to permit said stud to :be more easily stripped or withdrawn when released by the removal of the key 16.

The upper girder o1f is supported upon the upperpeud of the studs 11+ with its inner flat face substantially co-incident with the corresponding face of the posts or studs and therefore, in the same vertical bers Thatis, each upper bracket 1()+ constitutes a coupling member for cooperation with the coupling member 13,VV in securing the girder to the upper end of the stud -11 and for this purpose is provided with a boss lihaving a transverse slot 15- for receiving a tapered key ,16'- similar to the key +16? while the companion coupling member 13- is bolted or otherwise secured to the outer face of the said stud -11 to extend upwardly from the upper end thereof and is provided with a lengthwise slot 17 open at the top for receiving the boss l4.

When the lower or upper girders -lor l' meet at an angle or corner of the building, the meeting ends are provided with a pair of brackets 10 or 10 and coupling members l3- and 13 those of each pair being in juxtaposed relation or integral with each other in which case one boss as 14:' or 14- and one tapered key as 16 or 16 is sufficient for each pair, by driving the keys ,16 and 16'V diagonally through corresponding slots 15 and V15 and across the outer edges of the overlapping portions of the coupling members -l3+ and -13'.- as shown in Figure 1.

A sheet metal plate 18,, Figure 9, is secured by bolts ,19, or equivalent fastening means, to the inner face or wall side of each stud,-l1 to project beyond the opposite upright sides thereof, and thereby, .to form stop flanges -18'v for the adjacent edges of the panels 12 which are placed from the outside between the studs and against said stops so as to substantially fill ,the intervening spaces between the lower-and upperggirdersand between the upright studs where they areheld in place by turn but tons on the outer faces of the studs as shown in Figure l.

That is, the parts 7-20? are mounted on pivotal bolts 21:- projecting from the outer faces of thestuds 11+ and extend radially in opposite directions a sufiicient distance so that when turned to one position, their opposite ends will overlap upon the outer faces of the adj acent ends of the panels to hold the latter against outward displace Vment and when turned to another position parallel with'the stud, will lie wholly between the opposite sides of the stud to per- ;mit the panel to be withdrawn outwardly or away from the wall.

The lower andupper faces of the brackets projecting beyond the flanges of the girder V. 1',V are substantially flat and disposed in planes substantially co-incident with the corresponding faces of the girder so as to rest squarely upon the upper ends of the studs l1 and against the underside of the floor panels as 22-, Figure 1.

An angle bar 23 has one of its flanges secured by rivets or other suitable fastening means to the lower face of the upper girder land its other flange projecting clownwardly therefrom in a plane substantially co-incident with the inner face of the irder so as to form a continuation thereof, and also to. constitute a stop flange 24i for the upper ends of the studs or posts and panels 12- as shown more clearly in Figures 2 and 4:, the inner faces of the upper edges of said panels being recessed at 25 to receive said flanges 24 while the upper end of the plate '18- is cut away at 26-, Figure 1, V, to receive the same stop flange 24 whereby the inner faces of both girders together with that of the panels and of the stud 1l and the inner face of the stop flange -2 l will lie in. substantially the same flat plane to form a corresponding flat face on the concrete wall as the latter is progressively built up against those parts.

The panels 12- may be made in sections of suitable height most convenient for handling and are placed edgewise one upon the other from the bottom upward as the work progresses until the spaces between the studs and girders are filled, said panels being preferably made of laminated wood and reenforced at the ends by cleats 12-,of such thickness that when added to that of the main body of the panel, makes the entire thickness of the panel through the cleats substantially equal to the corresponding thickness at the studs so that their inner and outer faces may be substantially coincident with the corresponding faces of the adjacent stud, while the buttons -20 engaging the outer faces of the cleats when turned at rightangles to the stud serve to hold the adjacent ends of the panels in engagement 'withthe flanges --18 and -24. r i The parts thus far described areused to Outer wallforms. When these girders andfposts are properly assembled or coupled together in the manner described, they are utilized to support the companion forms forthe opposite faces of the wall, and for this purpose, the

'lower and upper brackets -10- and-10' and their corresponding girders 1]and 1 are provided with transversely registering bolt openings 27-' for receiving suitable tiebolts 2 8'-, the intermediate portions of the studs beingprovided with similar bolt openings -27 for receiving similar tie bolts 28, all of said bolts being free to slide'in' their respective openings and are provided at one end with heads -30- adapted to engage the outer faces of the brackets -10 and 10 andstuds 11 for limiting their movement in one direction. j

All of the tie bolts 28 and 28'+ are of substantially the same size and therefore, interchangeable, andare of suflicient length "to extend through and some distance beyond the wall space for receiving and supporting concrete spacing sleeves -band a metallic stop plate -31- against which, the companion panels 32 are adapted to rest when placed in operated position.

The spacing sleeve preferably consists of concrete blocks precast to the desired length corresponding to the thickness of the wall which is to be constructed and are formed with central lengthwise openings ,b-5 therethrough for receiving the tie bolts -28- and 28 said concrete sleeves being incorporated in the concrete wall to re- I plates 31- which are apertured to receive said bolts are placed over the smaller ends thereof and against the adjacent ends of the sleeve -Z) and are then locked in place by means of tapered keys 34 passing through transverse slots 35 in thebolts adjacent the outer faces of the stopplates 81- so that opposite edges of the key 34 will be wedged against the plate 31 and opposite wall of the slot 35 7 surfaces of the outer walls of a building and clamping the bolts to the brackets '10- and 10' and to the studs 11 independently of the panels 32 and -1Q.

These plates 31 are adapted to be used as a part of the form for'the outer may be made of any suitable lengths convenient for-handling and assembling, end to end, one upon the other during the progressive building, as the studs and girders for the various floors are erected, said plates being preferably of less width than the op posite stop plates -l8 and are provided intermediate their upright edgeswith outwardly projecting vertical flanges 36-- at one side of the bolt openings so as to form dividing partitions between the adjacent edges of the panels 252.and also to form stop flanges againstwhich'the inner faces of the upright edges of the panels may abut to limit the inward movement ofsaid panels.

These panels -32- are somewhat similar to the panels '12 in that they are made of laminated wood and provided with re enforcing cleats '32- near their opposite upright edges, the only difference being that they are-somewhat longer-to correspond approximately to the distance between the flanges 36 of the plates The outer end of each tie "bolt 28 and 28 extends between the adjacent ends of the panels -32 and some distance beyond the outer faces of the cleats 32-- and are provided with transverse openings 37-- for receiving tapering keys '38 which engage" metal wearing plates 39 on the outer faces of the cleats -32 and also engage the outer end wall of the slot 3T- for clamping the adjacent ends of the panels between the wedge and opposite edges of a.

the stop plate -31 and also permitting the removal ofthe panels independently of said stop plates by simply removing the key F Z001 forms.

The floor panels 22 upon which the concrete floors are made are supported upon the upper faces of the girders -1 and brackets 10' and are additionally supported by one or more floor joists 40- which are preferably made of light sheet metal of the I-beam type supported edge: wise vertically by the girders through the medium of suitable coupling members presently described with their-upper faces in substantially the same horizontal plane as that of the girder 1- for receiving and supporting the meeting ends of the panel sections, the latter being provided on their under sides with stop cleats 22 adapted to engage one side of the joist for properly alining the panels therewith and holding them against endwise displacement so that the ends'of the panels may meet along the longitudinal center of the upper face of the joist, it being understood that the joists are assembled on thegirders in spaced relation, a predetermined distance apart and that the panels are made of corresponding lengths and therefore, standardized.

The means for coupling the ends of the joist to the girders is shown more clearly in Figures 2 and 3, and comprises a pair of brackets 1I' secured at one end by rivets 42 to the web of the girder 1 within the channel thereof, and in longitudinally spaced relation slightly greaterthan the thickness of the web of the joist, the other ends of said bracketsbeing provided with a pair of horizontal slots l3 and a vertical slot 44' registering with simi lar slots in the web of the adjacent end of the joist 4O forreceiving tapered keys '45 and 46 whereby the joist is detachably supported by the brackets and may be released therefrom by simply removing the Wedges.

Thatis, the portions of the brackets having the slot-s 43' and 1% extend some distance beyond the flanges of the girder 1- so that the joist may be placed be tween them from'the underside upwardlyand locked in place by the insertion of the keys +45 and 46 in their respective openings in the brackets and joist, thereby temporarily holding the joist in operative position and permitting the same to be removed by downward displacement by simply removing the keys after the concrete floor has been formed.

Operation.

The footing-course or foundation a' having been previously'form'ed and leveled,

the girders 1' with the brackets10' tapered keys 16+, and the buttons 20 adjusted lengthwise of their respective posts.

The upper girder'sections with the brack-' ets 10' thereon are then placed in operative'positio'n upon the upper ends of the post and clamped thereto by means of the The floor joists are then liftedinto place and coupled to the girders by means oftaperedkeys +45'and 46'- thus producing a selfrsupporting skeleton structure for receiving the inner wall panels -l2 and floor panels *22 which, as previously stated, are made in easily portable sections for convenience in handling'and are placed in operative position by hand, the wall panels -12- being. held in place by turning the buttons 20 crosswise of the studs so as to overlap upon-the cleats of the adjacent panels.

In placing the outer forms for the walls in operative position, the tie bolts 28 and 28 are first inserted through their respective openings in the brackets 10 and 10, girders 1 and 1", and posts 11, until their heads rest against the inner faces of the posts and brackets, after which the concrete sleeves -6 are placed over and upon the outerends of the portions of the tie rods which extend across the Wall space. H

The stop plates 3 1 are then placed over and upon the protruding ends of the tie bolts and together with the sleeves are clamped in place by the keys 35 ready to receive the outer panels -32 which are placed in operative'po'sition by hand and are clamped in place by the keys -38 thus producing a vertical space between the panels for the reception of the concrete wall which may be filled in from the top and may be continued across and upon the floor panels 22 so as to homogeneously unite the concrete of the floor and walls into a monolithic structure.

The lower edge of the lowermost panel 32 rests upon the footing course -w while the several panels may be arranged edge to edge one upon the other, and carried to a height above the level of the floor line when necessary.

After the concrete wall and floor are completed and properly set so as to be self-sustaining, the forms may be stripped and reused for the next succeeding story for economy in the use of a limited number of forms although it is evident that as soon as the concrete floor is finished as a" unitary part of the wall, other form sections similar to thosedescribed may be used in, the con-' struction of the second story and superposed floor and so on through the several stories.

In stripping the forms from the completed walls and floors, it is simply necessary to remove the keys 88 whereupon thepanels 32- may beremoved one by one from the top'downward and laid aside,

after which the keys -35'- may be re moved thus permitting theremoval of the plates 31, sleeves 4 and bolts +28 The buttons 20'may then be turned lengthwise of the studs 11-" to permit the removal of the wall panels 12 after which the keys '16 and 16' and +45 and 4:6, and if necessary the key be removed to permit the 're- -7- may moval of the parts held thereby in such order. as may be most convenient, winch, of

7. course, would allow the floor panels +29%- to drop away from the Concrete floor for parts of the form shown and described also enables those parts to be standardized and used extensively for various kinds of work on the same or different buildings, and also reduces to a minimum the amount of mate rials necessary to carry in stock for such forms.

A further and more important advantage of this structure is that it avoids the use of nails, screws or similar fasteningmeans in that all parts are secured together by tapered keys or buttons which are easily removed or adjusted to permit the removal of those parts.
